虚拟频谱分析仪的设计及研究

内容简介：频谱分析是信号处理中的一种重要分析手段，各种频谱分析设备是工程分析以及高校教学科研的常用测试仪器，传统的频谱分析仪体积庞大、价格昂贵，功能单一，本文以 LabWindows/CVI 为软件开发平台，完成了虚拟频谱分析仪的设计，同时验证其正确性和可行性，从而弥补传统仪器的不足。

Abstract：Spectrum analysis is a very important method in signal processing. Various spectrum analysis facilities are common testing machines for engineering and teaching & scientific research. However, the traditional instrument is bulky and expensive with single function. In this paper, a virtual frequency spectrum analyzer based on the LabWindows/CVI software development platform was designed and its validity and feasibility were verified .
